  1. Age-Related Macular Degeneration By Tom Boyles, Dustin Broadus, Lori Buckle, Constance Marsh, and April Seybold

  2. What is Macular Degeneration? Macular Degeneration is a group of progressive eye conditions which involve deterioration of the macula, the central region of the retina. Partial list of types of Macular Degeneration: • Age-Related Macular Degeneration • Juvenile Macular Degeneration or Macular Dystrophy • Stargardt’s Disease, a type of Juvenile Macular Degeneration

  3. RISK FACTORS for MACULAR DEGENERATION • Smoking • Family history of the disease • Obesity • High blood pressure • Having a lighter eye color • Possible side effect of some drugs

  4. SOCIETAL IMPACT • Age-Related Macular Degeneration (ARMD or AMD) is the most common cause of irreversible vision loss in Americans over the age of 60. • Estimations say 10 million Americans will experience ARMD during their lifetime.

  5. There are two general types of Age-Related Macular Degeneration: • “Dry” (non-neovascular or atrophic) • Early stage, less severe • 85%-95% of cases  • Most common symptom is burry vision  • 3 Stages: Early, Intermediate, & Advanced • “Wet” (neovascular or exudative) • More severe than “Dry” ARMD • Early symptom: Straight lines appear wavy • Central vision blind spots develop • Two sub-types: Occult & Classic

  6. How is it diagnosed? If retinal damage is suspected, an ophthalmologist will perform a retinal exam.

  7.  Fluorescein angiography is used to examine the retinal blood vessels. • In “Wet” ARMD unwanted, proliferating blood vessels leak blood & fluid causing permanent damage to light-sensitive retinal cells. • In “Dry” ARMD yellowish waste deposits, called drusen form on the retina.

  8. An Amsler grid assists with diagnosis  An Amsler grid is a tool that eye doctors use to detect vision problems resulting from damage to the macula. The lines may look wavy if you have Early “Dry” ARMD. Small blind spots may appear in your vision as dry macular degeneration progresses.

  9. CHANGES IN THE MACULA

  10. What impact does ARMD have on the vision? • Distorted Vision • Loss of sharp, central vision needed for reading, driving, etc. • Difficulty seeing fine detail • Difficulty seeing color clearly

  11. Common Treatments • There is no cure for “Dry” or “Wet” ARMD at this point in time. • No FDA-approved treatments exist for “Dry” ARMD. • Studies indicate taking vitamins A, C, and E, zinc, lutein, antioxidants, & Omega-3 oils may help prevent or slow “Dry” Macular Degeneration.

  12. Common Treatments Various FDA approved drugs are used to slow down the progression of “Wet” ARMD. • Lucentis, Macugen • Visudyne used with Photodynamic Therapy or PDT

  13. What will improve the lives of individuals with ARMD? • Low vision aids such as magnifiers • UV protected sunglasses • Proper lighting for near tasks • Regular visits to your ophthalmologist or optometrist
